## Homework Statement

Four long straight wires located at the corners of a square of side

*l*= 27.8 cm carry equal currents

*I*0 = 16 A perpendicular to the page as shown in the figure above. Determine the magnitude of

**at the center of the square.**

*B*## Homework Equations

B=mu0/2pi*I/r

## The Attempt at a Solution

I know that using the equation above I will get the magnetic field. But does it matter that it's asking for the magnetic field at the center? Also when doing the x and y component, I am not sure how to find the angle. Is it just 90 because it's perpendicular?
